📌 What is Chronological Age?
Chronological age is the exact amount of time a person has lived since their birth date.
It’s usually expressed as:
- Years
- Months
- Days
For example, if someone was born on May 10, 2000, and today is September 12, 2025, their chronological age would be 25 years, 4 months, and 2 days.
This is different from biological or developmental age, which measures physical or mental maturity. Chronological age is purely time-based.
